This is a clip cutting out from the video called "The discovery of kyo kara maoh Vol.3".This is a new short story called "This is the relationship of partners.

The story is about Yuri get a backache one day, then Conrad and Ken try to help him. Ken gives Yuri a pain patch, and Yuri asks Conrad for help. After Conrad pasted the pain patch onto Yuri's back, he discovered that his hand is pasted onto Yuri's back too! The reason behind is that the pain patch is invented by the "Red hair devil"(i.e.Anissina-san)...and the pain patch has a very strange name likes the other inventions(haha!).
Yuri tries to separated himself from Conrad and moves his body but Conard asks him not to do so. Otherwise, they may totally be pasted together!(haha~)Then Ken thinks that Yuri looks like a doll controlled by Conard. When Conard asks Yuri not to move rudely anymore, the story also comes to an end~I hope this may help you understand the story.
